Context of the Lesson Where does this lesson fit in the curriculum and instructional context? Is it the opening of a unit or a series of lessons?
This is the middle of a unit of bonding, but we will move from ionic bonding to covalent bonding. This is an introduction to covalent bonding.
Opportunities to Learn
Definition: Materials, Learners and Environments
Plans to differentiate instruction: I will be using a lot of the board to give a visual representation as well as explaining in a verbal way. Also, I will have class problems that they will do as a class so they can learn through both intra and inter personal ways.
Accommodations and modifications: I will pace the lesson as I seem fit. If the I notice that they are understanding I will increase my pace slightly, but if there is struggle I will make sure to slow down.
Environment factors: The desks will still be set up in groups so they can always work together.
Materials: Paper and something to write with and a chalk board.
Objectives
Students will be able to define terms such as polarity, diatomic, and molecular compound. Students will be able to compare a molecular compound to an ionic compound.
Instructional Procedures
Opening: Welcome to the next part of James bonding. I will talk to the class and clear up and problems that there are with the discussion or if they have any last questions about the previous topic of ionic bonding. I will bridge by saying that not all compounds are ionic there are many things in this world that are considered to be covalent. I will take a few minutes to dissect the word covalent (We know about valance electrons so with that in mind can someone tell me what they think CO VALENT means?) Trying to get them to say co sharing valent meaning valance electrons. So now that we know a covalent bond is a sharing of electrons instead of a donation of electrons like we saw in ionic bonding.
Engagement: Once we get through what covalent means I will get into a small note session about terms and trends that will needed to be understood to understand a covalent bond. I will start with the idea that understanding octet and valance electrons will still be an important topic to understand. A quick review of both even though they should still be in their short term memory.What is the octet rule?Give me valance electrons of Na Cl and N. Now that we know the octet rule we need to apply this to covalent bonds. We understand from the beginning of class that covalent bonds share valance electrons. So that means for instance of the Hydrogen ion, if there are 2 H then that means that the molecule now has 2 electrons. This means it has a full shell of electrons. Therefore it contains a single covalent bond. In covalent bonding atoms are trying to obtain noble gas electron configurations.What are the noble gases?How can we tell if they have a noble gas configuration? Now show electron configurations or water or simple diatomic molecules. Review the trend of electro negativity, and then have the term polarity defined.I will ask them to tell me the electro negativity trend. Explaining that tomorrow remember this trend because we will be using this from tomorrow on. Go over electron dot structures, I will review them again in the next lesson but this will get them thinking electron dot. I will do this by putting formulas of molecules online and as a class they will walk me through the creation of the structure.Is there a difference in electron dot structures between a covalent or ionic bond?What does the line I drew here mean? Closure: Read through sections 8-1 and 8-2 and come to class with questions you have. Pay attention to the octet rule and the use of multiple bonds. And let me know tomorrow if you have any trouble with electro negativity trends.Assign book problems so that they can strengthen skills.
Assessment
None for this lesson. Just the observation of students and their prior knowledge throughout the lesson.
